Try starting with a larger ring first. If this does not hold your erection then try the next smaller size.
Remove ring within 30 minutes after using. Remove by rolling it off or by pulling the tabs forward. The penis will become flaccid as the ring is removed.
Do not use again for at least 60 minutes. Do not fall asleep with ring in place.
Your penis may feel a little cool and appear bluish in colour. This is normal as the penis ring slows blood flow and traps blood in the penis.
If using the constriction ring becomes painful or produces extreme coolness, bruising or discolouration of the penis, remove the ring immediately and consult your doctor.
